[Pr. PD31_Master-slave operation - Slave-side speed limit
coefficient (VLC)]
Initial value
0 [%]
For the speed limit command value received from the master axis, set the coefficient to reflect to the internal speed limit value.
This servo parameter is enabled only in the slave axis torque mode (slt).
This function corresponds to [Master-slave Velocity limit coefficient (Obj. 2E45h)].
When the object is mapped to the cyclic communication, do not write values with engineering tools because the controller
overwrites the servo parameter values written with engineering tools.
When this servo parameter is set to "100", the coefficient is multiplied by 1. The setting example is described below.
Ex.
[Pr. PD31] = "140"
[Pr. PD32] = "300" and
the master side is operated with an acceleration/deceleration of 1000 r/min:
Speed limit command

× [Pr. PD31] [%]
[Pr. PD32]
300 r/min
0 r/min
[Pr. PD32_Master-slave operation - Slave-side speed limit
adjusted value (VLL)]
Initial value
0.00 [r/min]
Set the minimum value of both the speed limit value and the setting value of [Pr. PD31 Master-slave operation - Slave-side
speed limit coefficient].
This servo parameter ensures torque control range at low speed driving (by avoiding area likely to reach speed limit). Set to
approximately 100.00 to 500.00 r/min in general. For the example settings, refer to [Pr. PD31].
Page 105 [Pr. PD31_Master-slave operation - Slave-side speed limit coefficient (VLC)]
This function is enabled when [Pr. PT01.1 Speed/acceleration/deceleration unit selection] is set to "0". This function and [Pr.
PV33 Master-slave operation - Speed limit adjusted value extension setting] are mutually exclusive.
The servo motor speed is clamped at the maximum speed. When changing the speed to the permissible speed, set the speed
in [Pr. PA28.4 Speed range limit selection].
This function corresponds to [Master-slave Lower limit of velocity limit value (Obj. 2E46h)].
When the object is mapped to the cyclic communication, do not write values with engineering tools because the controller
overwrites the servo parameter values written with engineering tools.
